To a!! whom. It may concern.'

Be it known that I Hanny Cos aan llamo, a citizen of the United States, residin at New York cit injthe' county of New ork and State of ew York, have invented certain new and 'useful Improvements in Tobacco-Stemming Machines, of which the following is a specification, reference being had therein to thc accom ianyingI drawing.

This invention 'rc ates to a tobacco-stemming or stripping machine.

In the accompanying drawings illustrating he brst forni now known to ine of embodyig the featuresof my invention Figure 1 is an elevation of one side; and liig.'2 is an elevation of the other side of the machine. Fig. 3 is a tof) plan view thereof.' Fig. L is an elevationa view, iartly in transverse section at line 1i-4. o Fig. 3, looking at .the dischar e or ejection .side of the strippm rolls. tig. 5 is a view iirtially in vertica section at line 5--5 of ig. 8, and partly in elevationaud mainly shows the auxiliar stem-gripping mechanism at the rear site of the stripp ng rolls which are shown in traiisversesection. A portion of' a wiper mechanism is also shown at the discharge side of lthe rolls.' Fig.' 6 isjan'elevatioinil view, partly in\seetion, at li ie G-- 'of Fig. 3; and shows mainly the mai and auxiliary stemgripping devices -and suine of their respective actuating and controllmgmechanisins.` Fig. 7 is an enlarged detail view nirtly in section, at l'ine'l 7`7 of Fig.I an

T strppm -roll wiper mechanism.- Heretofore in tiis class of machines great ditiiculty has been met in etting the stripped leaf blade away -from` t e stri Jpingrolls without injury to the leaf blade n rolls (or more particular y the lower roll throughout their length and also the-.com 79, the Wiper 70 extending transversely of the ,present ymachine vthc desired result is accomplished, by means of a wi er that clears the the machine and being connected at each c iid' to a sprocket-chain 71. Thereare4 two sprocket wheels 72one journaled' on lone side frame andthe otherjournledon the other side 'frame of'v the machine. Below each s rocket wheel 72 there is a sprocket wheel 8 journaled on a sidel 'frame of the ma/chine. Nearer 1the front endof the machine, its side frames are each provided with a thereon-journale'd sprocket wheel 74,v and each chain 71 rims over threes rocket wheels 72, 78 and 74. As the sproc et4 wliecls- 72 and 78 are mounted one above the'othe'r at veach side of the machine, 'the transverse wi'per.:70 is moved during its wiping o era- .'tion' when adjacent to the stripping rol s, in l an approximately vertical path, and, this movement is downwardly and perpendicularlv to the plane 4of the horizontal travel of the leaf and stems. Each sprocket wheel 74 1s mounted 'on the transverse 'shaft 75,

which has a sprocket-wheel 76 from which i 12C a sprocket-chain 77 extends around a s rocket-wheel 78 on shaft a (Fi s. 2 and). .he'wiper is shown as u brns and it is timed in its movement so as to bring -italieeossively int'o wiping relation with the leafblade present at the ejection side of .the stripping rolls, and into contact with the stationary transverse comb 70 preferably provided ou the under stripper-roll' (Figs.

4 and 8). This transverse wi )er serves efficiantly `to clear the4 rolls an conibof the i but the upper runs o of the machine. At one side of et'I ' pair of rolls stripped blade and to strike the stripped 'leaf downwardly free of the receiving comb as herein described, without injuryto the leaf. The transverse wiper during a portion of its travel comes into the path of the main stem-gri s from the feed-table to the strippiii`g-rol s, and consequently must .be moved out of such path when the wiping or clearance is effected in order that the next suc' ceeding pair of main stem-gri s may travel along that path.; The sproc et-wheels `72 and 74 are accordingly located in a plane above the sprocket-w eels 78 the s rocketwheels 72 and 73 being located one a ove the other, as above noted, adacently to the stripping rolls. Cerise uent y in its wiping movements, the wiper 7 travels downwardly out of said path and, while mainvstem-glrips ieir are traveling from the'feed end. of

ath to the stripping rolls', the wiper is raveling toward he feed end cfthe machine below the path of the main stemgrips; and, after turning about shiift '75 wh ch ls below said at it follows said ips and ogerates on t e leaf blade stripped y the,rol from, the stems h eld by such grips. This wiping mechanism may' be ce ed a main stein-grip dodging, wipingmechanism.

Between `this belt an the feed end of the machine a similarbslt 81 is located, the belts travel in op.- posite directions. lranie A is rovid with a-vertical partition 82 (I iigs.- and 8)- which rims from near the op s dI edges of these belts, and a traiisve y-extending roller is journaled in' the sides of frame A with its upper side just under the horiaantal path of the main stem-grips. Roller @0 is rotated by means of a gear 84 on its shaft and a gear 85 fixed on a journal 85* of the sprocket wheels 72. Theup r sur fece .of the roller'travels toward e feed end of the machine. Cons uentl roller 83 etici-ds a support over whic the caf drags as'it is being carried by the main steingriis from the feed-table to the strippingrcl s and ii a stem breaks in such travel of the leaf, the roller tends to'feed the leaf released from the Vmain stemgri backwardly in the direction ofthe feedble and, to discharge such unstemmed leaf on belt 81. rI `he partitions: 82 reventa the unstemmed leaves discharge on belt 81 from being in ed with the stemmed product falling/3 c.. t 80, and the unstemmed leaf and stemmed leaf are conveyed to op osite sides y I e machine, a horizcntallyxtending'shaft 87 carries a 88 over one of which belt 80, and over the other o# which belt 81, extends.

The stem-grip weilanden-Aia it occao'dhally ha pens that a stem will break at an un esired point between the strippixigrolls l and the stem discharging' end of t e machine (and at a ppint inthe stem short of the usually desired break which is ordinarily about one-third of the stem length from itat-ip)1 auxiliary stemgripping mechanism lwhic like the wi ing 35 mechanism, must dodge the main s emgri s is located between the strippiiigrolls an the rear end of the machine, ad1acently to the rolls. This auxiliary mechanism comprises a .transverse upper stem-gripping bar 00 and a transverse under stem-gripping bar 101 which first. grip the stein after the Ymain stem-grips have pulled the stem a sufficient distance rearwardly of the rolls. The ends ofbar 100 are secured tox side sprocket-chains 102, and the ends of bar 101 are secured to similar chains 103 (Figs` 5, 6, 2 andv 8). Each.- chain 102 .runs over sprocket-wheels 104 and each chain 108 runs over sprocket-wheels l105. The four u per sprocket-wheels 104, two at each side o the are carried by transverse shafts 106 an 107. The four under sprocketwheels are carried, two at each side of the machine, by transverse shafts 108 and 109.

To compelthe gri bars 100 and 101 to travel inproper wor 'ng relation for seizing and releasing the stem, shaft 107 has a r 110 which meshes with a ar 111 on s 'ft 109. Shaft 107 has a ,driving s rocket '112 from which a s rocket-chain 1 8 runs over a sprocket-wh 114 on shaft a (Fig. 8). The adjacent runs of upper chains 102 and of under chains 10% carry the auxiliary grip-bars 100 and 101 in the, ath of the main stem-grips 7 and 8 (see igs. 5 and 0), and the upper s rockets 101 and lower sprockets 100 are hel l spaced properly apart in the vertical direction by the brackets in which the shafts 107 and 109 are journaled, the endl of theauxiliary gri -bars being bont at 116 (Fig. .6) for suci connection with rocket-chains 102 and 103 as sulces to old .their transverse ortions in the ath of the .main gripars 7 and 8.
